A couple of months ago, a number of team Hacksung/CyanogenMod members expressed frustration and doubt regarding the fate of the popular custom ROM when it came to Samsung's newest flagship - the Galaxy S4 (see our review). Other CM members quickly put an end to the misinterpretation, but not before some prematurely jumped to incorrect conclusions. Needless to say, when Steve Kondik, a.k.a. Cyanogen, took to G+ to announce the first upcoming S4 builds, he couldn't resist the opportunity for a healthy dose of sarcasm:

His follow-up messages confirmed that the T-Mobile and Canadian S4s were first in line, followed by the international i9505 at some point in the future when the team gets a hold of the hardware, though it's not clear whether the i9500 or other Exynos Octa variants will be supported.

It was only yesterday that Cyanogen definitively confirmed AT&T's treacherous move to lock down the Galaxy S4's bootloader, but there is light at the end of that tunnel. No thanks to AT&T but to security researcher extraordinaire and a person I admire Dan Rosenberg, a.k.a. the magician, a.k.a. the root whisperer.

Dan, who is responsible for numerous root and unlock exploits, tweeted this photo of his Galaxy S4 earlier today:

There are no instructions or blog posts explaining the unlock at Dan's blog yet - these should be coming in the future.

After a short delay, Sprint is now ushering Samsung's highly anticipated successor to the popular Galaxy S III to store shelves, but how much does it cost? New customers can pick up the Galaxy S4 with a two-year contract for $149, but existing customers looking to upgrade must plop down $249 to bring home the same phone. This isn't the best of news for current Sprint customers, but there is now another option available.

I'm at Radio City Music Hall checking out the Samsung Galaxy S4. Tell me, have you seen the Galaxy S3? Then you've pretty much seen the GS4. There have been a few cosmetic tweaks, and a spec bump, but it's mostly a "Galaxy S 3S."

The screen is probably the biggest upgrade. It's been fitted with a 5-inch, 1080p AMOLED display, and it looks gorgeous. The viewing angles are perfect.

Well, the day is here, boys and girls – Samsung's newest flagship is a go. As expected (and never doubted), it's called the Galaxy S4, and it picks up where the GSIII left off. Offering even more eye-tracking features, more horsepower under the hood, and a few tricks from the Note II's playbook, the GS4 is a worthy successor to the world's most popular Android phone. Let's get down to the nitty gritty.
